To all whorn it may concern:

Be it known that 1-, ARCHA Frasvon, a citizen-of the United States, and a resident of Galesburg, in the county of Knoxand State of Illinois, have invented .a newand useful Device for Operating Air-Cocks on Air-Brake Cars, of which the'followingisa specification.

My invention has relation to means for turning on or off (or, as it is termed by railroad men, cutting in or cutting out) the air on air-brake cars.

On cars equipped with air-brake apparatus the angle-cock in which is seated the valve, is located to one side of the center of the car, or in other words, at the right hand side of the'car-coupling. The air hose extending from one to an adjacent cock is below the coupling and angularly thereof, or crossing it: It will thus be evident that in cutting in or out the air by the employment of the ordinary wrench or spanner, the brakeman or other operator must. reach across'the car coupling in order to reach the distant angle-cock,

to the great endangerment oi his limbs or even life.

The hand lever now in use is necessarily very short, and because of the constant exposure of the car and theclose fitting of the valve, itis often a difiicult matterto operate the latter. The usual expedient adopted is to reach-up with the foot and kick the leveran0ther dangerous operation.

The primary object of the invention is .to providef means whereby theoperatormay ,cut in orout the air without stepping between the cars, and in the employment of which means all risk ofinjury is eliminated. Another object is 'to -provide means whereby the valve may be turned with but little, effort.

Subsidiary objects appear as the nature of the invention is better understood.

The invention consists in novel constructions and combinations of devices, the operation of which def-"j vices will be found hereinafter fully described set forth in the claims hereto appended. Mechanism embodying the preferred constructive forms of, and showing the mutual relationship and combinations of the partsiorming-the subject matter way box-carfirrnished with y v V r the, (for instancehtirrned om; Fig.' 2 is'a vation oi the mcker, seen from the side nextthe Figure 1 is a .iront partly broken'awaying d'rawingsfln which:..

on appliances oi this'kind or character. It comprises a tubular portion8 which extendsunderneath and is supported by the carin any suitable manner, in which tubular portion the'valve (not shown) is seated, and'a threaded end or nozzle 9 to which a short section of hose 10 is coupled in the usual manner. It is furnished -in idway between the abutments '11 and projects a slight distance thereabove. The last described parts are also well known constructions and form no part snugly over the valve-stem 121 by means of an aperture for perfect operation, and are rigidly held discom 'nection by means of a pin 15. The poweratm 16 of the lever i ssplit, and to it is pivotally connected the head of a pitman rod 17 which is provided at its distant end with a series oi apertures 18. I

Directed through brackets 19 at each'side ofthe car are push or (as the case, may 20, :21, each provided grip or handle 22 and each pivotally p get each of the series of aperf:turs'.2 8- and tnl and prevents endwise movement of the-dink" the channel. After the required adjust-f -desiiribed,fa-lag-screw33 ispassed through other registering'a emueszs and stand its point threaded into ivtredtd the upper end of the link so, and the bar 21 Inthe drawings, to which reference is to. be had in 7 indicates an angle-cock such as is in general use with a semi-circular projection at its upper portion, the ends of which projection constitute abutments 11,. for afpurpose presently related. The valve-stem (which is fixedto or integral withfthe valve) is located I therethroughl Both are preferably angular form \connectedltoone member of an adjustable rocker 23 Apin32ispassed' represents the end of a box-car 2, the deadwood; I 3, the bufling plate; 4 and 5, other ordinary metallic ordinary construction and need not be further herein v of my. invention. A .lever or other eccentric means,. thehead llr of which is provided with a boss 14 is fitted merit o'fthe rocker members has been effected as last end'aa a'fulcrum for the rocker. The bar 20 is the following, to wit to the lug 25. the pitman being; pivoted in tin.- swivel 27 in any suitable manner.

Assuming the parts to be in the relative positions shown at/Fig. i, the. operator, standing at either side ot' the car and entirely free .theret'rom'. will draw on either bar-.20 or 21, whereby the rocker will move counter-clockwise and the lever will act on the valvestem 12 to shut oil' the air. 'loo great movement. in either direction is prevented by reason at the lug l-t striking againstan abutment 1.1 in an evident manner.

The swivel-yoke effectually prevents binding or sticking' of the pitman. Other advantages of the invention will be apparent and the operation understood from thei'oregoing description, it being particularly noted thatw'ai'iotts changes may. be made in the details of construction without. departing materially from the essential spirit of the invention.

.IHa ving thus set forth the construction and operai;;i01 1,. the purposes and advantages of the invention, I claim as new and desire to secure by Letters Patent 1."'lhe combination in a device of the character described,;wii;h a valve-stem, of means adapted to reciprocate it, and adjustable means engaged with said means and with a car and adapted to oscillate the first named means.

2 The combination 'in a device of the character described, with a'valvc-stem. of means adapted to reciprocate it, means for limitingtheextent of movement thereof. and adjustable'means attached to said last named means and to a can and adapted to oscillate the first named means.

3. The combination in a device of the Character described, with a. valve-stem, of means adapted to reciprocate it, a pitinan' pivoted thereto, an adjustable rocker to which is pivoted, and means for actuatingsaid means adapted to en"- said sit-tn. a pitman pivoted to said eccentric mcans. a rocker I'uicrnmcd on the Pill. means to! pivotaiiv connecting: it and the pitnian. and an at:- tuatingimr pivoted to each end of the rocker.

ii. The combination in a device of the character titscrihed. of an air-cock inciuding a valve-stem and abut. ments. a ievcr zniapt'ed for engagement. with said stem and to be limited in its movements by said abuim nts, a pitman connected to said lever. a rocker including a swiveled member'to which the other end of the pitman is secured. and means pivoted'to each end of the rocker for actuating it.

T. In eombinatioi in a device of the character described. with a valve stem. of a lever adapted to actuate. it. an adjustable rocker fuicrumed on the car and pivoted to the lever. and means adapted to be operated from the sides of the car for actuating the rocker.

S. in combination, a valve-stem. eccentric means secured thereto. a rod pivoted to the eccentric means, adjustable oscillator-v means to which the rod is pivoted, and means whereby said oscillator means is actuated.
